Example Reports and Calculations

A selection of early reports mostly collected together in an attempt to illustrate how with repetitive type projects, automation of the calculations can be incrementally implemented as move from one project to the next. Example: Portable Building My first calculations...

Wind Speeds and Topography

The wind loading code is based on the flow of fluid parallel to a flat plate. The plate can have roughness, this roughness is measured by roughness length (z0), and converted to terrain category. Appendices to AS1170.2:1989 contained charts for surface roughness...

Barrier Heights, guard rails and hand rails

As I seem to have difficulty explaining the difference between handrails and guardrails and when each is needed, I have added an XY chart to my balustrade design spreadsheet so that I can illustrate the different situations. Handrails and guardrails are not the same...

A Study Tour Wind Loading of Structures

The beginnings (eg. table of contents) of a  guided tour through various aspects of the wind loading of structures. Qualitative Overview Beaufort Windscale Chart The Recent Adelaide Wind Storms Related to Australian Wind Loading Code Design Wind Speeds for South...
